I have one of the DMM's. Myself and two friends was at a store a couple years back and they had them for $19.95 each. All three of us bought one. Last time I asked the two friends still had theirs for a spare and mine is in my garage for use at home. Not great quality, but will get you by in a pinch. I doubt it would hold up being used daily.
my Y/J has made in USA cast in the aluminum with the flag as well
Yup, you have the real YJ, but yj also imports this pump. Its not on there site, but if you order a special size you have to request which one you want.
I order a bunch of 1.5 for my guys, some were the real yj, some were the china one. I called yj and had a very indepth conversation with them about it. The china ones still have YJ on them, and we have not had any problems with the ones we have used, but any new one I order is specified as the real one.
